• Samples with extremely high doses (Ecstasy: more than 200 mg MDMA; blotter paper: more than 250 μg LSD).

​​

• Samples with unexpected ingredients whose effects occur later compared to the expected substance and which therefore pose a risk of overdose.

​​

• Samples that contain other psychoactive substances instead of or in addition to the expected substance, the consumption of which poses an acute health risk or is potentially life-threatening.

​

• Samples containing two or more psychoactive substances whose combination poses a high health risk or has unpredictable effects.

​​

• Samples with new psychoactive substances whose effects are not yet sufficiently understood, but which are suspected of posing a high risk.

​

In general, the risks of using psychoactive substances always depend on you, your current state of mind, and your environment. The risk categories we provide serve only as a general framework for substance warnings. Be sure to pay close attention to the information on safer use, as well as drug, set, and setting. Use drug checking services whenever possible.
